SPECIFICATION forming part of Letters Patent No. 570,409, dated October 27, 1896.

Application filed July 15, 1896. Serial No. 599,210. (No model.)

To all whom it may concern: thereon, are and may be all as usual in spin- Be it known that 1, JOHN T.

Upon this ings, is a specification, like letters on the roving-bar I have attached, by a suitable drawings representing like parts. screw a, myimproved roving-guide, the same This invention has for its object to improve consisting of a loop a, of Wire, more or less 60 and simplify those parts of spinning machincontracted at its lower end to guide the rovery which serve to guide the roving to the ing, the lower ends of the wire being turned rolls for drawing or reducing the material in upwardly to be acted upon by a suitable the process of spinning. washer or plate,to be described, (marked a My invention consists, essentially, in a peforming part of a clamp.

The part c has at its front end an eye and Ihave divided the stop-lever in two parts, with a portion 0, on which rests the yarn y, 85 so that the front part, which supports the passin g from thefront rollsto the usual guidethread between the rolls and the usual guideeye f, mounted on the thread-board g, the eye, may be moved without affecting the rear said thread when unbroken normally acting part, which is attached to the roving-clamp. on said part c to keep its rear end 0 pressed Figure 1, in section through the rolls, shows upwardly against and keep elevated the part 0 4 a sufficient portion of a spinning-machine d of the roving-clamp.

with my improvements added to enable my The roving-clampconsists,as herein shown, invention to be understood. Fig. 2 is a rear essentially, of a piece of wire bent into the or right-hand elevation of the parts shown in form of a loop (1 and located between the Fig. 1. Fig. 3 is an enlarged detail of the main and the auxiliaryroving-guide, as fully 5 stationary member of the roviiigclamp, and represented in the drawings, the said loop Fig. 4 shows a modified form of roving-guide having a cross-piece 3, which, when the loop adapted to control two rovings rather than descends, as will be described, due to break one roving. Fig. 5 is a top or plan view age of the yarn, will clamp the roving beth-ereof. tween itself and the recessed seat It in the mo 5 The roller-beam A, its stand A, and the cooperating part a of the washer, before resets of rolls A mounted in suitable bearings ferred to. The clamp d is normally kept elevated during spinning and when the thread is unbroken by the part (Z of the stop-lever. The opposite end of the stop-lever has a hook (Z and just below said hook Ihave provided the roller beam with a series of loops wt, preferably connected together and extending from one to the other end of the frame, said loops being adapted to be turned up into the dotted-line position shown in the drawings to engage said hook, the loops when engaging the hook preventing the descent of the roving-clamp, yetpermitting the front part c of the stop-lever to be elevated and the guideboard turned up for the purposes of dofling. During dotting it is not desirable to clamp the roving.

In case it is desired to control two rovings for each enlargement of the roll, I then shape the roving-guide as represented in Figs. 4 and 5, those figures showing the guide nearest the rolls and marked at as widely separated and the auxiliary guide n substantially in line with it, the roving being passed between the legs of the auxiliary guide and out side the legs of the main guide, as represented in Fig. 5.

During spinning and while the yarn is unbroken the parts stand in the full-line position shown in the drawings and the rovingbar is reciprocated, carrying with it the main and auxiliary roving-guide; but in case the yarn breaks the front end 0 of the stop-lever rises, letting the rear weighted arm (Z drop, it pulling down with it the clamp d causing it to clamp the roving between itself and the part h of the washer (t the action of the rolls pulling 011 the yarn separating the roving and leaving an end substantially touching the rearmost rolls, so that when the operator shall have taken the end of the thread from the bobbin and led it through the guide-eye and pulled down the end 0 of the stop-lever, the downward movement of the lever starting the machine, he can readily piece up the roving in usual manner.

If the bobbins are to be dotted, the operator throws up the loops or catches m, constituting locking devices, to engage the hooks d of the rear parts (Z of the stop-lever, and thereafter the thread-board and the front part c of the stop-lever may be freely lifted without clamping the rover.

Having described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. The rolls, a guide-bar, and a loop-shaped roving-guide attached to said bar, combined with a roving-clamp also made as a loop and a connected stop-lever, to operate, substantially as described.

2. A set of rolls, a roving-bar, two rovingguides attached thereto, and arranged one behind the other, and a stop-lever, combined with a loop-shaped roving-clamp arranged between the said two roving-guides and adapted to be moved to clamp and break the roving passing from one to the other of said guides when the stop-lever is not held by the thread between the front rolls and guide-eye, substantially as described.

3. In a spinning-machine, a set of rolls, a roving-bar provided with a roving-guide, and a seat, and a two-part stop-lever, one of which is provided with an adjustable weight, combined with a roving-clamp made as a loop and jointed to the weighted part of said stop-lever, to operate, substantially as described.

at. A set of rolls, a thread-guide, and a twopart stop-lever, one of said parts having a hook combined with a locking device to engage said hook and render inoperative one part of the said stop-lever leaving the other part free to be moved as required for dotting the yarn, substantially as described.

5. The roving-bar, the seat 71, and main and auxiliary roving-guides, arranged one in front of the other, all attached to said bar, combined with a loop-like clamp arranged between said guides and cooperating with said seat, and a connected stop-lever, to operate, substantially as described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

JOHN T. MEATS.
